-===== Why takes linking with ''g++ -g''  ages? =====
-This happens with older versions of gcc, seen with 3.3 on debian sarge.
+==== Authentication ====
-Use ''-gstabs'' or ''-ggdb'' instead of ''-g''. For debugging, this is better suited to c++ code and works with the GNU utils and most other debugger, too. (But unfortunately  not with /valgrind/.
+In theory, it should be possible to specify username and password
+  - in ''$HOME/.dodsrc'' and ''$HOME/.netrc'' (see below for an example)
+  - as part of the URL for example ''https://XXXX:YYYY@thredds.met.no/thredds/dodsC/....nc''
+Example ''$HOME/.netrc'':
+<code>
+machine thredds.met.no
+    login XXXX
+    password YYYY
+</code>
+Example ''$HOME/.dodsrc'' (replace ''YOURHOME'' with the value og ''$HOME''):
+<code>
+HTTP.NETRC=YOURHOME/.netrc
+</code>
+Unfortunately, this does not always seem to work as expected.
+Known status of OpenDAP authentication support (applies to ''fimex'' and ''ncdump''):
+  * Specifying the password in the URL does not seem to work when the password contains a ''/'', at least for Ubuntu 18.04.
+  * For Ubuntu 16.04 (xenial, EOL), both URL and netrc seem to work.
+  * For Ubuntu 18.04 (bionic), username and password cannot be read from netrc, but can be specified in the URL.
+  * For Ubuntu 20.04 (focal), username and password can only be read from netrc, but cannot be specified in the URL.
